AUGMENTER COOLER.

Application filed'April lo, 1923. Serial No. 631,107.

To aZZ whomit may concern:

Be it known that I, PAUL A. Biiuonii, a citizen of the United States, a resident of Nutley, county of Essex, and State of New Jersey, have invented a certain Augmenter Cooler, of which the following is a specification accompanied by drawings.

This invention relates to condenser units, but more particularly to the augmenter coolor adapted to be connected to a surface condenser for devaporizing and cooling a flowing mixture of condensable vapor and gas passing from the condenser. The lat ter part of the total heat abstraction then takes place in the cooler.

The object of the present invention is to enable the steam from the augmenter ejector on the cooler, to be condensed by means of a spray of water, so that the multiple cooling surfaces in the intercooler, which form part of the cooler, cool the air passing through the intercooler chamber as in the usual manner, and are not relied upon to condense the steam from the primary jet of augmenter ejector.

Another object of the invention is to insure that the water from the additional spray nozzle shall flow over the multiple cooling surfaces of the intercooler and aid in the cooling action.

Further objects of the invention will hereinatter appear, and the invention is shown in one of its preferred forms in the accompanying drawings, in which Figure 1 is a side elevation of a condenser unit showing the invention,

F igure 2 is an end view of the condenser unit,

Figure partly in and Figure 4 is a detail plan view of a form of hatfle used in the intercooler.

Referring to the drawings, the condenser A is preferably a surface condenser adapted to be provided with cooling tubes (not shown), and maybe of wedge shaped form in which the mixture of condensable vapor and gas, as steam and air is admitted at the top, and after passing downwardly over the condensing surfaces, passes out at the bottom through the outlet B.

The present invention is particularly concerned with a cooler or that portion of the condensing apparatus in which the latter 3 is an enlarged detail side view longitudinal section of the cooler,

part of the total heat abstraction takes place. The cooler G, in this instance, in the form oi an augmenter cooler, is adapted to be incorporated with the condenser A, and is preferably arranged against the lower portion of the one side of. the condenser, as shown in Figures 1 and 2, and at an angle to the vertical axis of the condenser. The cooler C is preferably oi? wedge shape or pyramidal form, although not necessarily of this form, in which the mixture of air and vapor coming from the condenser after the major portion of the steam has been condensed, passes up ardly through the cooler, which is provided with multiple cooling elements or surfaces D, substantially of the form shown in my prior Patent No. 1,380,- 460, granted June 7th, 1921. A suitable evacuator as a vacuum pump, or a secondary steam jet E, shown in Figures 1 and 2, may be connected to the cooler as for instance at the outlet E. The function of the. cooler as well understood, is to complete the condensation of the vapor as the mixture flows from the surface condenser, and in accordance with my construction, the cooler includes a devaporizer comprising the chamber F, and the intercooler comprises a cham- 361 G forming a part of the cooling apparatus. One or more augmenter ejectors H of the jet type may be arranged to discharge steam into the inter-cooler G- to increase the absolute pressure ot air in the intercooler.

lVater is supplied both through the cooling elements of the condenser A and through the cooling elements of the cooler in any suitable manner and as shown, the water is supplied at the common water inlet J and passes through the condenser to the discharge outlet K. ater also passes through the inlet pipe L to the inlet O of the cooler and is discharged from the cooler through the outlet 1?, and from thence passes to the discharge pipe Q on the condenser.

The discharge outlet R of the devaporizer chamber F and the inlet S of the intercooler chamber G, are arranged side by side and a cover T carrying the augmenter ejector H forms the cover of the cooler and connects the said outlet R and inlet S. By placing the augmenter H on the cooler and ejecting from the devaporizing chamber F to the intercooler chamber G the air from the devaporizer is compressed from absolute pressure to increased absolute pressure in the intercooler. A certain volume of steam would be added to the mixture from the augmenter jets H and it is desirable that this steam or most of it be removed by condensation in the intercooler thus reducing the cubical contents going to the vacuum pump, or the ejector, at the outlet E. The cooling in the intercooler reduces the steam pressure, While the total pressure remains the same and thereby increases the air pressure and raises the volumetric efficiency on the vacuum pump. Since ordinarily there Would not be sufficient cooling surfaces in the intercooler to properly condense the steam from the ejector H, I provide a water spray nozzle U suitably mounted on the cover T and arranged to s1 ray Water into the inlet of the intercooler chamber Gr, so that the steam from the ejector is condensed at this point. A baflie V is preferably connected by brackets to the Wall. of the intercooler at a point opposite the spray nozzle U so that the spray Water and the condensate is drawn over the multiple cooling surfaces or grids D of the intercooler. Any Water Which collccts at the outlet E of the intercooler is returned to the space X in the cooler by the by-pass pipe Y, and is drawn off through the outlet B of the condenser.

The apparatus is provided with the condensate pump Z of any suitable or usual form, which Withdraws the condensate from the condenser, and I prefer to connect the spray nozzle U on the cooler, with the discharge pipe at of the condensate pump, as by means of the pipe I), so that the condensate is used as the Water for the spray nozzle U and this has been found to be a satisfactory and economical arrangement.

I claim:

1. An augmenter cooler adapted to be connected to a condenser for devaporizing and cooling a flowing mixture of condensable vapor and gas, comprising a devaporizer and an intercooler forming a part thereof, both having multiple cooling surfaces, an augmentor ejector operatively connected between the discharge outlet of the devaporizer and the inlet to the intercooler for increasing the absolute pressure of said mixture, means for spraying water into the inlet of said intercooler to condense the steam from the augmenter ejector, and an evacuator connected to the outlet of said intercooler.

2. An augmenter cooler adapted to be connected to a condenser for devaporizing and cooling a flowing mixture of condensable vapor and gas, comprising a devaporizer and an intercooler forming a part thereof, both having multiple cooling surfaces, an augmenter ejector operatively connected between the discharge outlet of the devaporizer and the inlet to the intercooler for increasing the absolute pressure of said mix ture, means for spraying Water into the inlet of said intercooler to condense the steam from the augmenter ejector, and a baffle in said intercooler opposite said Water spraying means for causing Water to pass over the multiple cooling surfaces of the intercooler.

3. In a condensing unit, the combination of a surface condenser, a condensate pump,

an augmenter cooler adapted to be connected to the condenser for devaporizing and cooling a flowing mixture of condensa-ble vapor and gas, comprising a devaporizer and an intercooler forming a part thereof, both having multiple cooling surfaces, an augmenter ejector operatively connected between the discharge outlet of the devaporizer and the inlet to the intercooler for increasing the absolute pressure of said mixture, a nozzle for spraying Water into the inlet of said intercooler, a connection from the discharge of the condensate pump to said Water spray nozzle, and an evacua-tor connected to the outlet of said intercooler.

In testimony whereof I have signed this specification.
